TP4056 lithium charger module - modification to add power sharing

I posted about this at the end of another thread, but wanted to provide a bit more information, and give it its own thread. This is a modification of the standard TP4056 charger module - the one with battery protection built in - to add the three components that make up a load sharing circuit - a logic level P-channel mosfet, a schottky diode, and a resistor. The OUT+ and B+ terminals of the module are shorted together, but if we cut that trace, and reverse the functions of those terminals, we …

or some such link, the modification is around somewhere.

How to modify TP4056 module.Setup low and high constant current. Install NTC temperature sensor.

words I used "tp4056 modification" in a search thingy.

And I had ordered 10 of those MPPT charge controllers.
